Control Seal DBBV provides 100% bubble tight sealing both up and down stream and is achieved mechanically - independent on line pressure. DBBV is a single valve solution used as replacement of two in-line valves with a drain and/or bleed valve.See all results for this questionWhat is an automatic control valve?Automatic Control Valves do not require an external power source, meaning that the fluid pressure is enough for opening and closing the valve.

Double mechanical seals are offered in two arrangements: Two rotating seal rings are arranged facing away from each other. The lubricating film is generated by the barrier fluid. This arrangement is commonly found in the chemical industry.See all results for this question
The pressure can be relieved to the pressure source or to the low pressure side, generally downstream. The relieving pressure in the body cavity shall not exceed 1.33 times the fully rated valve flange rated pressure. The single piston effect seat design in the API 6D is also called the Double-Block-and-Bleed (DBB) Valve.See all results for this questionWhat is a Double Seal and When to Use One (Double Seals double sealed automatic control valveDouble seals are a must-have for certain applications in many countries; These seals are increasingly used by companies to meet specific environmental goals or emissions requirements. A properly installed double seal also allows for near complete control over the seal operating environment and fluid film over the seal faces. This factor alone can greatly maximize seal life.What is a Double Block and Bleed Valve? - Crane EngineeringA double block and bleed valve is like having three valves in one. API 6D defines a double block and bleed valve as a "single valve with two seating surfaces that, in the closed position, provides a seal against pressure from both ends of the valve with a means of vending/bleeding the cavity between the seating surfaces."
Cla-Val automatic control valve products perform with precision and accuracy to provide exact pressure, flow, level, surge and pump control. As pioneers in water supply and distribution systems, our proven automatic control valves are specifically designed to meet the requirements of todays municipal water utility systems. From municipalities requiring durable, low maintenance valves that can handle ValvesToday double sealed automatic control valve3.Because of double eccentric structure design ,the semi-ball valve is perfectly sealed and can be closed tightly . 4.When the valve is closed ,the wedding force is able to remove the foreign materials ,therefore it has anti-scaling performance.ValvesToday double sealed automatic control valve2.Since the metal sealed bidirectional rotary ball valve is offered with self-sealing device,reliable sealing performance can be realized under the pressure from medium. 3.Powerful specific pressure of sealing can be obtained the valve is installed on the direction in opposite to that of the fluid.The pressure acts on the valve seat of the double sealed automatic control valve
A double mechanical seal consists of two seals arranged in a series. The inboard, or primary seal keeps the product contained within the pump housing. The outboard, or secondary seal prevents the flush liquid from leaking into the atmosphere.

A cost efficient yet technologically-sophisticated alternative to liftable and balanced double-seat valves.
Functional Description. With Südmo Double Seal Valve, two incompatible media (e.g. CIP and product) can be separated in the pipelines without mixing and contamination. This is ensured by two separate seals, between which an open air space enables any potential leaks to be detected and removed. Additionally, the leakage chamber can be externally flushed by two valves fitted on each side.NFPA Required Inspections of Fire Sprinkler ValvesInspecting valves in a fire sprinkler system Control valves . The interval for inspecting a control valve which is any valve controlling flow to water-based fire protection systems depends on whether the valve is secured and monitored: From the 2017 Edition of NFPA 25 . 13.3.2 Inspection. 188.8.131.52 All valves shall be inspected weekly.Learn About Steam | Control Valves | Spirax SarcoAs the name implies, the double seat valve has two valve plugs on a common spindle, with two valve seats. Not only can the valve seats be kept smaller (since there are two of them) but also, as can be seen in Figure 6.1.3, the forces are partially balanced.
